Heat therapy helps relieve pain by increasing blood flow to the affected area, relaxing tight muscles, and improving tissue flexibility. It is especially useful for chronic conditions such as arthritis, muscle stiffness, and spasms, as well as pain caused by tension or stress. Applying heat can soothe aching joints and muscles, reduce stiffness, and make movement easier. Common forms include heating pads, warm towels, hot showers, or warm baths, typically used for 15–20 minutes at a time.
Cold therapy, also known as cryotherapy, works by reducing blood flow to an injured area, which helps decrease inflammation, swelling, and pain. It is most effective for acute injuries like sprains, strains, bruises, or flare-ups of joint pain. Cold numbs the area and slows nerve signals, providing fast pain relief. Ice packs, cold gel packs, or even a bag of frozen vegetables wrapped in a towel can be used for 10–15 minutes at a time, especially within the first 24–48 hours after injury.
